Evaluate {(30 + 6) - 3^2} divided by 9 x 2 a) 6.6 b) 6 c) 1.5 d) 34

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
